Thunderchiefs in an air strike against a surface-to-air missile (SAM) site north of Thon Cam Son and west of Đồng Hới, north of the DMZ in North Vietnam. Day was on his 65th mission into North Vietnam and acting as check pilot for Captain Corwin M. "Kipp" Kippenhan, who was upgrading to aircraft commander. 37 mm antiaircraft fire crippled the aircraft, forcing the crew to eject. In the ejection, Day's right arm was broken in three places when he struck the side of the cockpit, and he also received eye and back injuries. Kippenhan was rescued by a USAF HH-3E, but Day was unable to contact the rescue helicopter by survival radio and was quickly captured by North Vietnamese local militia. On his fifth night, when he was still within 20 miles (32 kilometers) of the DMZ, Day escaped from his initial captors despite his serious injuries. Although stripped of both his boots and flight suit, Day crossed the DMZ back into South Vietnam. Within 2 miles (3 kilometers) of the U.S. Marine firebase at Con Thien and after 12 to 15 days of evading, he was captured again, this time by a Viet Cong patrol that wounded him in the leg and hand with gunfire. Taken back to his original camp, Day was tortured for escaping, breaking his right arm again. He then was moved to several prison camps near Hanoi, where he was periodically beaten, starved, and tortured. In December 1967, Day shared a cell with Navy Lieutenant Commander and future senator and presidential candidate John McCain. Air Force Major Norris Overly nursed both back to health, and McCain later devised a makeshift splint of bamboo and rags that helped heal Day's seriously atrophied arm. On 14 March 1973, Day was released after five years and seven months as a North Vietnamese prisoner. Within three days Day was reunited with his wife, Doris Sorensen Day, and four children at March Air Force Base, California. On 4 March 1976, President Gerald Ford awarded Day the Medal of Honor for his personal bravery while a captive in North Vietnam. Day had been promoted to lieutenant colonel and then to colonel while a prisoner, and he decided to remain in the Air Force in hopes of being promoted to brigadier general. Although initially too weak to resume operational flying, he spent a year in physical rehabilitation and with 13 separate medical
